[1'0 (1Z1 whom it may concern i Be it known that 1, WILLIAM F. CLARK, a

citizen of the United States, residing at Coraopolis, in the county or Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Furnace-Charging Apparatus, of which the following is a can, clear, and exact description, reference had to the accompanying drawings,

1w forming part of this specification, in which-- Figure l is a plan view of a machineembodying'my invention; Fig. 2 is a side elevation, of the same; Fig. 3 is a section on the line Hie-HI of Fig. 1; and Fig. 4 is a section on the line IV-lV of Fig. 3.

. will hereinafter more fully appear.

Referring to the accompanying drawings, in which I have shown the preferred embodiment of my invention and which will now be described, the numeral 30 designates the framework of the charging bench, which is supported on wheels 31, engaging the tracks 32.

33 designates a table or support mounted on said frame and on which the skelp 34 to be charged into the furnace 35 is stacked.

36' is a suitable trough or guide for the skelp.

37 designates feed rolls which are journaled in the frame 30 transversely thereoi. These rolls are arranged inpairs, the two 'rolls of each pair being placed side by side and separated from each other laterally, at least, at their peripheral portions, by a distance less than the width of the skelp or other pieces to be charged into the furnace. The rolls of each pair are rigidly secured to a transverse shaft 38, which is driven by suitable gear connections 39 with a longitudinal shaft 40. The shaft 40 may be rolls.

driven by any suitable means, such as the electric motor 41, mounted on the trance 30. The rolls are preferably so placedthat their peripheral portions will extend slightly above the bottom of the trough 36, as best shown in Fig. 4.

Below each pair of rolls is an electromagnet 42, having pole pieces 43, extending upwardly into the space separating the two rolls. The upper end portions of these pole pieces are curved inwardly from opposite sides, as indicated at it, their adjacent ends being separated by an air gap at 45. The outer surfaces of the portions 44 of the pole pieces are curved to conform approximately to the circumference of the rollers 37, but are slightly below the peripheral surface of such rolls, so that the skelp will at all times be held by the rollers out of contact with the pole pieces.

I prefer to make the rollers of non-magthey maybe removed suliiciently far away from the furnace so as not to be ailected by the heat thereof, and if necessary, they can beefiiciently protected from such heat when placed close to the furnace, without in any wayinterfering with the operation of the apparatus. The magnets can also be made of any size necessary to give the required tractive force, irrespective of the size of the Inasmuch as the magnets are stationary, it is not necessary to provide circuit connections between moving parts for energizing the magnet windings. The arrangement of the magnetic pole pieces-relatively to'the rollers is also such that the magnets are effective so long as any portion of the skelp is on the rolls.

For charging large sizes of skelp, it is desirable to employ two sets of rollers 37, as shown in Fig. 1. For smaller and lighter skelp, however, one set of these rollers may be omitted and a single pair, properly located, may be employed instead.

Various other changes may be made in the details of construction and arrangementof parts, without departing from the spirit and scope of my invention as defined in the appended claims.

I claim: 4

l. A furnace charging apparatus, comprising a pair of feed rollers of nonmagnetic material, said feedrollers being close to each other and arranged to rotate about a common axis, and a magnet having narrow pole pieces on opposite sides of the axis of the rollers and between the rollers; substantially as described.

2. A furnace charging apparatus, comprising a pair of feed rollers of nonmagnetic material, an axle to which said rollers are secured, there being a narrow space between said rollers, means for rotating said axle, and amagnet having narrow pole pieces on opposite sides of the axle nd between the rollers; substantially as desc 'ibed.

3.A furnace charging apparatus, comprising a carriage adapted to be moved transversely in front of the furnace, a table on said carriage'for supporting the blanks to be charged into the furnace, a'longitudinal trough, a pair of rollers of nonmagnetie material below the trough and extending into the lower portion thereof, said 'feed rollers being close to each other and ar ranged to rotate about a common axis, and a magnet having narrow pole pieces on opposite sides of the axis and between the rollers for drawing the pieces to be charged into contact, with the periphery of both rollers; substantially as described.

4. A furnace charging apparatus, comprising a carriage arranged to be moved transversely. in front of a furnace to be charged, a table on said carriage for the blanks to be charged into the fuinace, there being a longitudinal trough on the carriagc for receiving the blank from the table, a pair of feed rollers below the trough and extending into the lower portion thereof, a

- shaft to which said rollers are secured, there being a narrow space between said rollers,

charged, atable on said carriage for the blanks to be charged into the furnace, there being a longitudinal trough on the carriage for receiving the blank from thetable, a pair of feed rollers below the trough and extending into the lower portion thereof, a shaft to which said rollers are secured, there being a narrow space between said rollers, means on the carriage for rotating the shaft, and an electromagnet supported on the carriage below the rollers having narrow pole pieces extending upwardly between the rollers on opposite sides of the shaft; substantially as described.

- 6. A furnace charging apparatus, comprising a pair of feed rollers of nonmagnetic material, said feed rollers being close to each other and arranged to rotate about a common axis, and a magnet below said rollers having narrow pole pieces which extend upwardly and inwardly toward each other about the axis and between the rollers; substantially as described.

In testimony whereof, I have hereunto set my hand.
